RemoteClinic 2.0 contains a critical vulnerability chain that can be exploited by a remote attacker with low-privileged user credentials to create admin users, escalate privileges, and execute arbitrary code on the target system via a PHP shell. The vulnerabilities are caused by a lack of input validation and access control in the staff/register.php endpoint and the edit-my-profile.php page. By sending a series of specially crafted requests to the RemoteClinic application, an attacker can create admin users with more privileges than their own, upload a PHP file containing arbitrary code, and execute arbitrary commands via the PHP shell.
The product allows the upload or transfer of dangerous file types that are automatically processed within its environment.
